8.6.4.11: Car and CW run-by
Procedure
Check the car and CW run-by to verify they meet code requirements. Note exclusions below:
8.6.4.11.1: The car and counterweight runby shall be permitted to be reduced, provided the car or
counterweight does not strike the buffer, the top car clearances are not reduced below that
required at the time of installation or alteration, and the final terminal stopping device is still
operational.
8.6.4.11.2 Where spring-return oil buffers are provided and compression was permitted with the
car at the terminals the buffer compression shall not exceed 25% of the buffer stroke.
8.6.4.18: Examine compensating sheave and switch
Procedure
• Examine and clean the compensating sheave and ensure it has not reached its upper or
lower limits of travel. Adjust, if required.
• Lubricate sheave bearings.
• Check to ensure the sheave moves freely. Lubricate the sheave frame with KONE bearing
grease (#
US59623), if required.
• Check operation of the compensating sheave switch to ensure it is mounted securely,
operates freely and removes power to the driving machine when actuated.
8.6.4.22: Maintenance of Seismic Devices (if applicable)
Procedure
8.6.4.22.1: Examine the seismic switch to ensure it is clean, securely mounted and activates
as designed.
